Specific embodiment
Be readily appreciated that, as shown in the accompanying drawings herein and general description and described in multiple components of the invention can be with
A variety of different configurations are to arrange and design.Therefore, below as represented by attached drawing and be described as follows for modification Multiple level with
Machine accesses the embodiment detailed description of system, method, apparatus and computer program product that channel (RACH) is transmitted, it is no intended to
It limits the scope of the invention, but the representative of multiple embodiments selected by the present invention.
Feature of the invention, structure or characteristic through specification description can be in one or more embodiments with any
Suitable mode is combined.For example, through the term " some embodiments ", " some embodiments " or other similar of specification
Language refers to that the specific feature described in conjunction with the embodiment, structure or characteristic can be included at least one embodiment of the present invention
In obtain the fact.Therefore, through the term of the whole instruction " in certain embodiments ", " in some embodiments ", " at it
In his embodiment " or the appearance of other similar language must not necessarily all refer to same group of embodiment and described feature, knot
Structure or characteristic can be combined in any suitable manner in one or more embodiments.
In addition, if it is desired, different function discussed below can execute in a different order and/or simultaneously with each other.
In addition, if needing, one or more functions in described multiple functions can be optional or can be combined.Cause
This, being described below should be considered as only to the principle of the present invention, the explanation of teachings and embodiments, rather than limitation ot it.
For for example, the maximum coupling for spreading over (EC) with 23dBm emission function mobile communication (GSM) IoT equipment
Closing loss (MCL) performance is 154dB, and in comparison, the MCL performance of the NB-IoT device with identical transmission power is 164dB.
For the gap between the technology of making up, improve the uplink performance of the EC-GSM-IoT device with 23dBm as much as possible
It is extremely important.In addition, the MCL of EC-RACH channel, which improves, is possible to phase because of its channel for being viewed as a limitation uplink performance
Compared with for other channels have more challenge.The number for only increasing blind physical layer transmission is not sufficient to realize required additional cover
Lid improves.
Therefore, it is necessary to for low-power EC-GSM-IoT equipment (for example, 23dBm transimission power) MCL improve so that its
Performance matches with other technologies.Specifically, the MCL improvement for EC-RACH may be significant challenge.Furthermore, it is necessary to minimum
Change the power consumption of the equipment between access and data transfer period.The embodiment of the present invention can be solved these problems at least.For example,
Certain embodiments of the present invention provides a new transmission mechanism, and the Multiple level for EC-RACH transmits, it is contemplated that not increasing biography
Additional covering gain is realized in the case where defeated number.
Current 2 time slots (TS) EC-RACH operation in 3GPP Rel-13 is as follows: by the covering of extension
Equipment transmitted in a manner of phase coherence in two continuous time gaps access burst transmission and the two access bursts
Sequence be repeated in continuous TDMA frame；And base station by two happen suddenly symbol carry out coherently in the same direction with orthogonal (IQ)
Combination, and timing advance (TA) is estimated first by searching for the training sequence code position (TSC).Once calculating timing to mention
Before, base station just uses training sequence to carry out channel estimation, and is further processed data bit to carry out channel decoding.
The embodiment of the present invention provides mixing double gap mechanism, and the mixing double gap mechanism is in the feelings for not increasing the number of transmissions
The performance of random access channel (such as 2TS EC-RACH) is improved under condition significantly and does not increase the number of transmissions.
As discussed below, an embodiment is related to a kind of new transmission mechanism for being used for double gap (2TS) EC-RACH,
Including the change to transmission mechanism provided by the 2TS EC-RACH in 3GPP Rel-13.According to one embodiment, from being used for
Two time slots (2TS EC-RACH) of Multiple level access burst transmission, do not transmit identical signal (that is, the first gap (example
Such as, time slot number 0 (TN0)) and the second time slot (for example, time slot number 1 (TN1)) on access burst), different letters
It number can be transmitted, for example, by using long burst, being used at the second gap (for example, TN1) at the first gap (for example, TN0)
Random burst, wherein long burst, which has, is longer than the length to happen suddenly at random.According to one embodiment, in the scene of GSM, long burst
It can have the length for being equal to standard burst.It is noted that GSM in standard burst refer to have specific quantity data and
The burst of training bits is (for example, in gsm, standard burst-length is that 148 symbols+8.25 protect symbol and access burst long
Degree is that 88 symbols+68.25 protect symbol).
In one embodiment, although burst is not identical, they can use phase coherence (that is, using between adjacent bursts
Given phase relation) transmitted.In one embodiment, not only access burst, and it is 0 that long burst, which also can use,
Timing advance (TA) is transmitted, without considering distance between mobile station and base station.By applying certain embodiments of the invention institute
The method of offer, it can be ensured that, still can be by base station two from remote mobile station (MS) by two accesses formed that happen suddenly
It is received in a time slot.
The multiple additional symbols transmitted in long burst can be used in long burst and send access burst
Multiple copies of coded data block.Therefore, it realizes in receiver end across long burst and the encoded data block of access burst
The relevant IQ of different instances is combined, for example, encoded data block (referring to fig. 2 to 4 copies of 4 and Fig. 7) rather than 2
Copy (referring to Fig. 1).If necessary to sensitivity improving, then the diacritic transmitted in long burst can be utilized to increase instruction
Practice sequence length and/or multiple copies with data.If not needing sensitivity improving (that is, it is not to be suitable for well covering
The focus of the equipment of lid), diacritic can be used more to transmit some information datas.
According to another embodiment, long burst can be exchanged with the sequence of access burst.For example, transmitted with TA for 0
It is the long burst transmitted with high TA after access burst, such as in the range of from 60 to 63.The TA of long burst can be pre-
Definition and independently of the distance between MS and base station.Equally in this case, burst can be used phase coherence and be passed
It is defeated.
In embodiment, when receiving transmission, base station can first be carried out the blind physical layer transmission of both bursts
IQ combination, and the starting based on the cross-correlation energy mark position TSC and burst.Long burst and the combination of access burst are by specific
TSC is identified, and the specific TSC is different from TSC as defined in EC-RACH is directed in 3GPP Rel-13.It is prominent identifying both
After the starting of hair, base station can identify the position of the different instances of the encoded data block in two bursts.Base station can be with
Using include both burst in encoded data block multiple copies come execute multiple data symbols relevant IQ combination,
Equalization data symbol and decoded data bits.In embodiment, to multiple after the equilibrium that base station can also happen suddenly at two kinds
Data symbol executes soft-combine, and the result combines combined use with relevant IQ most preferably to be decoded.Of the invention is multiple
Embodiment can generate the link level performance better than 3GPP Rel-13 2TS EC-RACH channel.
In one embodiment, if TA MS transmission BS order and corresponding to distance between MS and base station, and
It is not timing advance is 0, then any can have ratio without change in access burst by the transmission of the access burst of MS
In the case where spy, it is extended to protective time slot (GP).In this case, MS can indicate the presence of added bit, this is additional
Bit is transmitted in protective time slot as the part of data bit.Using 60 possible bits as RACH protective time slot
In the case where (total GP=68.25 bit), it is possible to send 24 payload, the 24 payload use is identical as data bit
Channel coding scheme be encoded.
Therefore, according to embodiment, if knowing that, by timing advance to be applied, MS can be in the usual number of access burst
Network (for example, base station) MS is notified to have additional information to transmit in RACH protective time slot according in bit.Because when base station receives
Access burst and when estimating timing advance, if timing advance is 0, base station and whether be unaware of MS genuine nearby or MS is
It is no to use the timing advance retained.Base station obtains the knowledge by decoding to data bit.The present embodiment, which is beneficial to improve, to be come
It is solved from the contention of the equipment of known timing advance, because additional 24 bit can carry the MS identity solved for contention
Some bits.
More generally, MS can be used than ordered lower TA (if since receive last TA order with
Carrying out MS may be already close to base station, then this will be helpful to the uplink reservation protection period in base station), and by being less than 60
Bit (this is needed in the case where TA of the application lower than order, and if this since receiving last TA order
Since MS may be useful in the case where the base station) extension access burst.If access burst is prominent in standard
It is transmitted after hair, then the extension of access burst can be used.Otherwise, although the most of embodiments and example of this paper refer to
In generation, happens suddenly followed by the long of access burst, and long burst and the sequence of access burst can swap.
Fig. 1 shows the existing 2TS EC-RACH transmission mechanism for the EC-GSM-IoT in Rel-13, uses 88 ratios
Special long access burst (AB) format.There are the tail bit of 8 extensions, 41 synchronizations for corresponding to and being known as TSC in section start
Sequence bits, 36 data bits (after coding) and 3 tail bits at the end of burst.GP=69 and GP
=68 are illustrated respectively in the quantity of the protective time slot bit at the ending of time slot number (TN) 0 and 1.In Fig. 1, Yi Jiru
Multiple embodiments of lower discussed Fig. 2 to 4 and Fig. 7, what is happened suddenly in TN0 and TN1 is transmitted as phase coherence.In addition,
In Fig. 1 to 4, two bursts are transmitted using TA 0.
Fig. 2 shows the double gap mixing EC-RACH using 2*TSC and 4* data bit block according to one embodiment
The example of transmission.In this embodiment, TSC is extended to 50 bits, and by comparing EC-RACH payload bit from 11
Spy is optimized to 7 or 8 bits, and data bit is reduced to 27 bits.What the 2TS EC-RACH compared to 3GPP Rel-13 was transmitted
The coherent transmission of 2* data bit block, this design provides the relevant of the 4* data bit block in two subsequent time slots
Transmission.In embodiment, (it is shown 3 protection bits between data bit section, for reducing between data bit section
Unknown intersymbol interference should not mutually be obscured with the protective time slot bit being located at the ending of time slot) and 3 tail bits
(it is shown before protective time slot) is identical as last 3 training bits (that is, TSC bit) respectively.
Fig. 3 shows 1 long TSC of use according to the embodiment with the double gap mixing EC-RACH's of 4* data bit block
Another example.More specifically, Fig. 3 shows the embodiment of the double gap mixing EC-RACH of embodiment, wherein according to one
Embodiment, TSC transmission is scaled up to 1.5 times of length (i.e. 62 bits), rather than repeats the TSC in the second time slot, and
Only data bit (and tail bit and protection bit) is transmitted in the access burst sent in TN1.In this embodiment,
TSC transmission is extended, rather than is crossed over 2TS and carried out cutting, and the access burst of TN1 only last bearer data bits.It is originated in TN1
10 extension tail bits in last 3 and 3 protection bits or tail bit after data (for example, 36 bits) section
Last 3 training bits are identical.Equally, in this embodiment, data bit can use in two subsequent time slots
Long burst and access burst transmit 4 times in TN0 and TN1.Block size is 36 bits, this in 3GPPRel-13
The block size of 2TS EC-RACH is identical.
Fig. 4 shows the double gap mixing EC- that use according to the embodiment has 1 long TSC among 4 data bit blocks
The example of RACH.In the embodiment shown in fig. 4, in last 3,3 protection ratios of 8 extension tail bits of burst section start
It is first 3 in special and data (36) Duan Suihou 5 tail bits, identical as preceding 3 training bits.
Fig. 7 shows the double gap mixing EC- that the centre according to the embodiment in 4* data bit block has 1 long TSC
Another example of RACH.Compared to Fig. 3, the sequence of burst is retained-and the access burst on TN0 is prominent prior to the length on TN1
Hair.Just like in general, not to access burst application timing advance.However, happening suddenly for long, using timing advance 63, to minimize
Gap between access burst and long burst, also, even if the distance between MS and BS are 35km, at base station uplink
There is sufficiently long protective time slot after long burst,.In the embodiment shown in fig. 7, in 10 expansions of access burst section start
Open up last 3 of tail bit and multiple data (36) Duan Suihou 3 protection bits or tail bit, with last 3
TSC bit is identical.Data (36) section can be identical encoded data bit block.
It is noted that in above-described embodiment (for example, Fig. 2,3,4 and 7), prior to or follow 3 tails of data bit section
Bit, protection bit or training bits are identical.Allow to terminate as grid balanced device after IQ accumulation known
Bit.
The selection of double gap mixing EC-RACH format can be broadcasted by network (for example, base station/eNB).For example, in order to
Signal notifies the payload of 11 bits, network can order equipment (for example, MS/UE) using having 1 long TSC and 4* data
The double gap mixing EC-RACH format of bit block can order conversely, transmitting shorter payload to signal
Use the double gap mixing EC-RACH format with 2*TSC with 4* data bit block.Among other parameters, double gap is mixed
Closing EC-RACH format also may include the sequence order (Fig. 2,3,4 and 7) of standard burst and access burst, and it is prominent to be directed toward access
The combination that hair happens suddenly with the standard with predefined burst structure.
One embodiment is related to a process, which includes being used for random access letter two continuous time slots
In the case of road transmission, for example, transmitting the double gap including a long burst by MS or UE mixes random access channel, wherein growing
Follow an access burst after burst closely.In embodiment, double gap mixing random access channel is double gap mixing EC-
RACH.It in embodiment, include attached in long burst (compared with two subsequent access bursts) when needing sensitivity behaviour
Bit and added bit is added to can be used for more repetitions of more training bits and/or data bit.It is sensitive when not needing
When spending performance improvement, added bit can be used for carrying some more information, such as, and if there is low volume data to need to transmit, or
It is to be transmitted quickly to carry out contention solution whether person has some identifiers to need.For example, the long burst after training sequence
First piece of the position of the added bit of transmission and subsequent data bit, can be used for first piece of blind object of data bit
Managing first piece of layer transmission and data bit can also be repeated one or more times in the second burst (that is, access burst).
Random access channel is mixed (for example, double gap mixes with the double gap of access burst including long burst when receiving
When EC-RACH), BS (or eNB) can identify the bit of additional transmitted after timing advance estimation, and include in number by them
According in the inphase quadrature combination of bit.Base station can also be broadcasted to equipment (for example, MS/UE) to use double gap to mix at random
Any format of channel (for example, double gap mixing EC-RACH) is accessed, and then, equipment can select for channel access
